I’ve configured MCU Boot in FSP3.8.0 to use external QSPI for the secondary slot which works when not coded. Still, if I enable ECISE encryption in RASC and put an coded image in the secondary slot in QSPI, MCU Boot will tell me that both the primary and secondary images aren’t valid. I’m encrypting with the python image tool using the test keys without any error from the tool. Does anyone have any ideas?
